Not without doing a lot of extra work. You're going from Renix to HO so the engine management is different. Ports are different too. Much easier to swap the motor entirely or swap a Renix head to your Renix block.

Yep. Really not worth it anyway. What are you hoping for?

If you own a Renix Jeep, you'll want to check this out.
